how do I see compiler errors?? [message #831967] Thu, 29 March 2012 11:28 Go to next message

I keep getting "Error: Could not find or load main class ..." error.

Finally wondering if the issue is some kind of compilation error that I'm not seeing. For the heck of it, I created a couple different errors that should have given me some kind of error msg upon compilation, but I don't see any! I tried creating an object that isn't defined, and I intentionally put a space in my println:
Syst em.out.println("Page title is: ");

This should create some kind of error somewhere, yes??
Where would I see it? I did have Build Automatically checked, tried unchecking, doing a clean, and it says that it will build after the clean, but I still see no error?? How do I get the errors to show?

Thanks
Glenn

What kind of project is the Java source in? If you are not working within a Java project the Java builder will not run on your source and no error markers will be created.

If you are working in a Java project, try opening the Problems View when your source is open in the Java editor and see if there is anything there.

I'm pretty sure that I created a java project.. is there any way that I can verify?

Also, the Problems view is one of the bottom panes? (Along with Javadoc / declaration/ search and console?) If so, there is nothing listed: "0 items"

Sad

OK, won't let me do links cause I'm under 25 msgs.. so I'll be editing them out..

I found the "Validate" option under the project, clicked it, and got the following in the Problem view:

Description Resource Path Location Type
cvc-complex-type.2.4.a: Invalid content was found starting with element 'pluginManagement'. One of ...:distributionManagement, "... maven.apache.org/POM/4.0.0":properties}' is expected. pom.xml /MySel20Proj line 16 XML Problem
------------

Would you know if this means that I need a new build of maven?

Eclipse opened the pom file for me to highlight the error (and possibly correct it I guess .. red "X" next to "pluginManagement"), but I wouldn't know what to update.

Thanks for looking at this

Select project, right click ->Properties. The list of properties on the
left should include Java Build Path, Java Code Style, etc. Builders
section should have Java Builder.

Also make sure that your source code is in a source folder.
Properties->Java Build Path->Source tab.

You might want to check out the Java development user guide Basic
Tutorial. It explains what needs to be done for Java development.

I had the same issue. The issue for me was my Java "Project Name" had spaces and a semicolon in the name. Renaming it worked.

Before: ICS; 2012-13
After: abcd

Worked when I renamed it to "abcd".
